Kasaantuminen
Kasaantuminen is a Finnish term describing the process by which discrete elements accumulate, coalesce, or gather into larger aggregates, arrangements, or piles in a given area or system. The concept is used across disciplines to refer to the buildup of matter, energy, or organisms through transport, interaction, and environmental conditions, with field-specific interpretations.
In geology and geomorphology, kasaantuminen refers to sediment accumulation: grains transported by water, wind, or ice
Mechanisms underlying kasaantuminen include transport by fluids or winds, gravitational settling, adhesion or sticking between particles,
